The effect of altitude on the regeneration in alpine skiing - a review study
Štanglerová, Magdaléna ; Šteffl, Michal (advisor) ; Brtník, Tomáš (referee)
Background Training at high altitude, historically in natural conditions and now in created artificially hypoxic environments, has been used to enhance physical performance in a wide range of endurance sports for many years. For alpine skiing, which takes place naturally at higher altitudes, prolonged exposure to altitude hypoxia and low ambient temperature is specific. However, even here, some effects of this specific load on the athletes are still unclear. Objectives The aim of this thesis is to summarize the results of studies dealing with the topic of hypoxic training in alpine skiers and its effect on selected physiological parameters. Methods The thesis is conducted as a systematic review in accordance with the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Four electronic databases were used to obtain relevant sources - Web of Science (WoS), PubMed, Scopus and SPORTDiscus using the EBSCO database. Results A total of 234 potential publications were retrieved, of which 15 studies including data from a total of 294 probands, mostly elite alpine skiers, were used in the final systematic review. Seven studies used the normobaric hypoxia method and eight studies were conducted under natural conditions. Five studies looked at the acute effect,...

Predictive validity of the all-out test of finger flexors for climbing performance
Štanglerová, Magdaléna ; Baláš, Jiří (advisor) ; Šteffl, Michal (referee)
Title: Predictive validity of the All- out test of finger flexors for climbing performance Objectives: The main aim of the study was to determine the predictive validity of the all-out test of finger flexors during climbing performance for competitive sport climbers in redpoint (RP), on-sight (OS), and bouldering. Methods: The work was carried out as a cross sectional study, in which the relationship among climbing performance and the results of all- out test was researched. The all-out test was implemented by a dominant hand according to the protocol on a specific climbing dynamometer 1D SAC (SpaceLAb Sofia, Bulgaria) on a 23 mm wide rung. The non parametric statistical Mann-Whitney U-test for continuous variables and chi-square test for categorical variables were used in data analysis. Spearman's rank correlation coefficient was used in the correlation analysis. A standardised Beta coefficient was calculated in linear regression models to assess the predictive validity of selected variables from the all-out test. Results: The tested group was consisted of a total of 31 mostly sport climbers aged 30.0 ± 8,6 years, of which 23 were men and 8 women. The highest statistically significant correlation among men was between OS climbing performance and the moment of force from the whole all-out test W...
